Abstract

An electrical connector used for inserting with an electronic card comprises a lengthwise insulation body and a conductive terminal. The insulation body is provided with a central slot and a terminal groove. An arm comprising a side arm and an elastic arm is arranged on the end part of the insulation body, wherein, the elastic arm is provided with a stopping block. The electrical connector also comprises a locating device for positioning the elastic arm. The locating device is provided with a baffle which can move together with the elastic arm. The side arm is provided with a raised block which can push against and hold the baffle. When a card is inserted in, the baffle is pushing against on one side of the raised block to prevent the elastic arm from deforming in large scale, thereby ensuring the structural intensity of the electrical connector. When the card is retreated back, the baffle moves to push against at the other side of the raised block and does not rebound back to prevent the elastic arm from moving back, thereby being convenient to pull out the electronic card.
